To make sill, take 10-inchi width lumber 1 inch thick and cut in seg- 

 ments of circle of wall; cut enough of these to make 3 or 4 inches thick; 

 put first in layer of mortar, then give a coat of gas tar, then lay on anoth- 

 er coarse, breaking joints; nail down to lower layer. Continue laying, 

 tarring and nailing till desired thickness is reached. We are now.ready 

 for the tarred staves or 2x4's. But you will wonder how to make a start, 

 what to use for fastening hoops and silo with, and what to fasten staging 

 to. To do all of this requires 4 timbers uf hardwood 4x6 inches in size 

 and as high as the silo is to be. Before w:- put these timbers, we bore 

 -enough holes in these sticks to receive the hoops. These holes are in 

 .pairs, and are 2y 2 inches from what will be the inside edge of silo. Holes 

 -are to be 3 inches apart long way of timber. Nov/ we will lay off our 

 .circle, finding % distance, where we stand one of these sticks and secure 

 it by toe-nailing to sill; again measure another V^, set up timber, and 

 <;ontiue till we have four up; we at the same time brace these pieces 

 well with fence boards or 2x4's,[ always keeping out of inside of silo. Af- 

 ter we have braced well, we set 2x4 pieces on outside of silo, opposite the 

 4x6 timbers, about 3 feet frm them, or as wide as you wish to build 

 scaffolding; nail lumber from these 2x4's at intervals of about 8 feet, 

 on which scaffold lumber is laid. A silo 25 feet high will require 3 of 

 these stagings. Now we are ready to set up these staves. Three men or 

 boys are needed for t his work. The tools necessary are 3 hammers and 

 plenty of 60-penny wire spikes; 40's will do in case 2x4's are scant 4 

 inches, a they often are. Now set up one of the 2x4's against a 4x6 piece 

 about every 4 feet; the men on different stages will attend to nailing up 

 to top of silo; toe-nail the 2x4 stave to sill with 10-penny wire nails. 

 Continue setting up and nailing; if the upper half of staves do not want 

 to fellow circle, strike on inside wall with heavy hammer, maul or back 

 of axe, and, the right curve will come. After setting all staves to lay 3 

 or 4 feet (and this space should be where doors are to be), make arrange- 

 ments for the doors. The doors are only the wall of the silo cut out on 

 bevel and the pieces thus cut out nailed together with some barrel 

 ^staves, the staves giving the short pieces the necessary curve to circle;
